高三复习-时间状语从句用法
时间状语从句用法
用法可以用八个字来概况:主将从现或主过从过。
主将从现:主句用了将来时,从句就要用现在时。
主过从过:主句用了过去时,从句也要用过去时。
时间状语
在复合句中,担任状语成分的从句称为状语从句。
时间状语从句说明主句动作发生或进行的时间。
状语从句由连词引导,其位置通常可以放在句首或句末。
放在句首时,常用逗号与主句分开;放在句末时,从句前面往往不加逗号。
引导的时间状语从句的主从复合句中,动作发生在先的用过去完成时,在后的用过去时。
表示前面的叙述所没有提到过的信息。
它总是对所描述的事件予以引人注目的强调,意为“这时;突然”;当位于句末的分句具有引种用法时,大致有以下三种情况:
A.when分句前面的分句使用过去进行时。
B.when分句前面的分句使用was (were)about to,was(were)on the point 等。
C.when分句之前的分句用过去完成时,其中sb had hardly/scarcely/barely … when已成为固定词组。
表示对比,主要有以下两种情况:
A.相当于whereas,while,since,意为“既然;然而”。
B.when从句中使用虚拟语气,意为“本来……却……”。
原因状语
原因状语从句说明主句动作发生或进行的原因,一般由because,since,as等引导。
because语气较强,用来说明人所不知的原因,回答why提出的问题。
当原因是显而易见的或者已为人们所知,就用as 或since 。

高中英语新高考语法基础版一轮复习讲义(一)三大从句时态知识点整理总结(含练习)
2021届高中英语新高考语法基础版一轮复习讲义(一)三大从句时态知识点整理总结(含练习)从句的时态是困扰很多同学的问题,尤其是想到六种从句和多达十几种时态的相互碰撞,就头疼不想看。
Part 1: 宾语从句的时态三定律定律一主过从过:当主句时态为过去时,从句一律要变为过去时态。
定律二主现/将|从不限:当主句为现在时或一般将来时,从句时态据实而定。
定律三从真理、主不限:从句为客观真理,用一般现在时,主句不限时态。
Part 2:状语从句的时态二连击定律四主将从现:主句为一般将来时,从句用一般现在时。
连接词一般为:when/as soon as/not...until/before等。
定律五一个过去用过去,两个过去用过完。
如果以现在为参照,以动作发生时间划分,最近的过去为G1,其次是G2。
主从都为过去,且二者有明显时间差,则G1为一般过去式,G2为过去完成时。
主从都为过去,二者同时发生或无明显时间差,均为G1,均用一般过去式。
Part 3:名词性从句的时态1. 当主句的谓语动词是过去式时,宾语从句若不是一个客观事实或真理,其谓语动词也必须用某种过去时态。
如:She said that she didn't want to know.她说她不想知道。
I asked her whether she would agree.我问她是否会同意2. when, if 这两个词既可引导名词性从句,也可引导状语从句。
当它们引导名词性从句且表示将来意义时,要直接使用将来时态;但当它们引导状语从句且表示将来意义时,则必须用一般现在时表示将来意义。
如:I don’t know when he will come, but when he comes, I’ll call you.我不知道他什么时候,但当他来的时候,我会打电话给你。
句中第一个when 引导的是宾语从句,故用将来时态表示将来意义;第二个when 引导的是时间状语从句,故用一般现在时表示将来意义。
主过从过,主将从现,主现从任
重温一道引起思绪混乱的题........After a wonderful meal, they told stories and sang songs by the campfire.表示“在……之后”的句式:after+从句/doing/n.after I arrived => After my arrival 在我到达之后完成同义句转换:when the plane arrived =After his arrival, we have a party. ==时态使用重大的规则:(12字原则)主过从过,主将从现,主现从任【主将从现】常见的有以下三种情况:一、When/if引导的主句是一般将来时,从句用一般现在时。
I'll tell her the good news when she comes back.当她回来的时候,我将把这个好消息告诉她。
If it doesn't rain, he will come here on time.如果不下雨,他会按时来这儿的。
二、如果主句是祈使句,那么从句要用一般现在时。
Don’t laugh at me when I make a mistake. 我犯错误的时候不要笑话我。
三、如果主句是含有情态动词的一般现在时,从句多用一般现在时。
You should be quiet when you are in the reading room. 在阅览室时应保持安静。
【主过从过】常见的有以下二种情况:1.直接引语变成间接引语2.宾语从句中,当主句的谓语动词为过去时态时,从句须用表示过去的某种时态。
例如:He asked when they would go to the party.他问他们什么时候将去参加聚会。
Miss Green said she had been to Beijing before.格林小姐说她以前曾经去过北京。

主将从现,主过将从过,主现从现
主将从现,主过将从过,主现从现-if句上个学期,我们曾经学过由if 引导的句⼦,你还记得吗?对了,“ I’ll not go to the zoo if it rains tomorrow. ( 假如明天下⾬,我就不去动物园。
) You can come to the party if you don’t wear jeans.(如果你不穿⽜仔裤,你就能来舞会。
)” 这个学期⼜在本单元见到了似曾相识的同样由if引导的句⼦,⽐如:“If I won the lottery, I would give it to medical research. (假如我赢了彩票的话,我就捐给医学研究。
) If I were you, I would wear jeans and T-shirt.(如果我是你,我就穿⽜仔裤和T恤。
)”这两个单元学到的句⼦都是由if引导的。
那么,它们有什么区别呢?对了,分两种情况:1.something may possible happen某事发⽣的可能性较⼤。
这种情况,有个⼗三字⼝诀:“主将从现,主过将从过,主现从现”。
即主句是⼀般将来时,从句⽤⼀般现在时;主句⽤过去将来时,从句⽤⼀般过去时;当主句中有can/can’t的话,则从句⽤⼀般现在时。
例如:If he has time, he will come tomorrow.If she finishes early, she can come back early.If you don’t do homework, the teacher will scold you.2.it is just imaginary, and nothing will happen 某事只是想象的,并不会发⽣,或者发⽣的可能性很⼩。
则要⽤我们常说的虚拟语⽓。
例如:If he were kind, he would help me with it. (He isn’t.)If I had more money, I would buy all of them. (I don’t.)If he were generous, he would give us a good treat. (He isn’t.)If you were tired, you would find a good job. (You aren’t.)If I were you, I would buy the dearest one. ( I am not.)任务设计任务I. 请⽤正确的形式填空。

主将从现 知识讲解 “主将从现”适用于什么样的从句中
主将从现知识讲解“主将从现”适用于什么样的从句中所谓的“主将从现”第一层次,即“主句用将来时(现在将来时和过去将来时),从句用一般时(一般现在时和一般过去时)”,这一层次也可以称作“初中层次”。
第二层次:“主将”中将来时有将来进行时,将来完成时,将来完成进行时,而“从现”中相应的时态也可能是现在进行时,现在完成时,现在完成进行时。
例如:If the snow has completely stopped, we will be playing with snow on the playground.如果雪能够完全停下来,我们将正在操场上玩雪呢!If it is snowing, we will have been walking in the snow for more than two hours.如果天一直在下雪,我们将在雪地里走了两个多小时了。
另外,引导条件状语从句的连接词(connector)还可以是unless, so long as, in case, on condition that, supposing that, provided that 等。
if引导条件状语从句的两种用法:第一种用法:当某事发生的可能性较大时,这种情况,有个十三字口诀:“主将从现,主过将从过,主现从现”。
即主句是一般将来时,从句用一般现在时;主句用过去将来时,从句用一般过去时;当主句中有can/can’t的话,则从句用一般现在时。
例如:If he has time, he will come tomorrow.If she finishes early, she can come back early.If you don’t do homework, the teacher will scold you.第二种用法:1.if从句还表示不可实现的条件或根本不可能存在的条件,也就是一种虚拟的条件或假设,从句多用一般过去时或过去完成时。
when的主句和从句时态
when的主句和从句时态“when”在英语中是一个引导时间状语从句的连词,表示某个动作发生的时间点或时间段。
关于“when”引导的从句与时态的关系,以下是一些常见的规则和情况:1. 主句与从句时态一致原则:当主句和从句的时态都是一般现在时或一般过去时,从句的时态不受主句影响。
例如:- I will call you when I finish work. (主句将来时,从句将来时)- We were eating when the phone rang. (主句过去进行时,从句过去时)2. 主将从现原则:当主句为将来时态(如will, shall, be going to等),从句通常用现在时代替将来时。
例如:- I will let you know when he comes back. (主句将来时,从句现在时)3. 主过从过原则:当主句为过去时态(如过去进行时、过去完成时等),从句也通常用过去时态。
例如:- They started to work when they had finished their homework. (主句过去完成时,从句过去时)4. 虚拟语气:在虚拟语气中,有时主句和从句的时态并不一致。
例如:- If I had known, I would have helped you. (主句过去完成时,从句过去将来完成时)5. 固定表达不受此限:有些固定表达不受上述规则限制,如“no sooner...than...”和“hardly...when...”。
例如:- No sooner had he arrived than he left again. (主句过去完成时,从句过去时)- I had hardly started when it began to rain. (主句过去完成时,从句过去时)6. 特殊的时态搭配:有时为了强调某个时间点或情况,主句和从句也可能使用不同寻常的时态搭配。

关于谓语动词正确形式的解题思路及技巧点拨
关于谓语动词正确形式的解题思路及技巧点拨作者:时一星来源:《中学生英语·中旬刊》 2020年第5期时一星判定谓语动词的正确形式是英语考试的重点和难点,涉及众多题型。
由于此类题目灵活多变,全面考察语法、语义、语境的综合分析能力,致使许多同学在做题过程中总是顾此失彼。
本文介绍的“三步口诀法”为这类难题提供了省时高效的解题思路和技巧。
1. 分清谓语动词和非谓语动词谓语动词通常是指置于主语后面作谓语的动词,受主语的人称和数的限制。
非谓语动词是指充当除谓语以外的其它句子成分的动词,不受人称和数的限制。
2. 谓语动词形式的解题思路及技巧第一步:看主谓定语态由主语是谓语动词的执行者还是承受者确定是主动还是被动语态。
请比较:Peter invited me to the party last week.Peter was invited to the party last week.注意:连系动词、不及物动词只有主动语态,及物动词或不及物动词+介词构成的短语,后面应跟宾语却缺少宾语时应为被动语态。
请改正:The woolen sweater is felt very soft.She heard to sing a song at the dance yesterday.He kept silent when he spoke to.第二步:判时态定结构语态和时态相结合可以确定句子结构,其中体现了谓语动词的时态、语态的变化。
(1)简单句的时态判断:主要由时间、频度状语、句意、语境来进行综合考虑。
1. 时态标志词法:—Where were you at this time yesterday? —I was going over my lessons then.(划线部分是过去进行时的标志词)。
2. 分析句意法:I heard that you were a talented pianist at college. Can you play it for me?Sorry, I(play) the piano for years. 我已经好几年(过去到现在)没弹钢琴了,所以应填haven’t played。

The teacher will be angry if he is late.If引导的条件状语从句与unless引导的条件状语从句的转换If+否定形式=unless+肯定形式You won’t pass the exam if you don't work hard。
If 的两种用法
“ 【1 】if”的两种用法|:一.意为“是否”时,引诱宾语从句.应遵守的时态是:①主现从随意率性.即:当主句为一般如今时的时刻,从句可依据本身的时光短语断定该用什么事态,不受主句的影响.②主过从过.即:当主句为一般曩昔时的时刻,从句应用曩昔的某种时态.③[留意:①宾语从句要用陈述语序,即:主语在前,谓语动词在后]Eg: He asks if I Like English. (主现从随意率性)He asks if I am going to the party this evening. (主现从随意率性) He aske d if I liked English. (主过从过)He aske d if I was going to the party this evening.(主过从过) 二.意为“假如”时,引诱前提状语从句.应遵守的事态是:①主将从现.即:当主句为一般未来时的时刻,从句应用一般如今时.②主现从现.即:当主句为一般如今时的时刻,从句应用一般如今时.③主过从过.即:当主句为一般曩昔时的时刻,从句应用曩昔的某种时态Eg: If you go the party, you will have a great tim e! (主将从现)If you ride your bike to school, you’ll be late.(主将从现)If you don’t have your ID card,you can’t go to the party.(主现从现)If you don’t listen carefully in class,you can’t do your homework. (主现从现)If you got up earlier this morning, you wouldn’t be late.(主过从过)If you didn’t finish your homework,the teacher would be angry with you.(主过从过)“if”时,要先断定“if”是哪种意思,再断定时态.Eg:Mary asks me if I will go to the zoo with her next Sunday;If it doesn’t rain, I will go with her.剖析:第一个“if”意为“是否”,所以它引诱的是宾语从句;又因主句是一般如今时,从句里的时光短语为next Sunday,所以从句该应用一般未来时.即:主现从随意率性.第二个“if”意为“假如”,所以它引诱的是前提状语从句;又依据高低句接洽,断定时光词也是next Sunday,所以主句该用一般未来时,从句该用一般如今时.即:主将从现.2.If引诱的前提状语从句可与“祈使句+and/or+句子(一般未来时)”这一句型互相转换.个中and暗示顺承,意为“那么”;or 暗示转折,意为“不然”.如:If you work hard,you will pass the exam easily.= Work hard,and you will pass the exam easily.=Work hard,or you won’t pass the exam easily.。

重温一道引起思绪混乱的题........
After a wonderful meal, they told stories and sang songs by the campfire.
表示“在……之后”的句式:after+从句/doing/n.
after I arrived => After my arrival 在我到达之后
完成同义句转换:
when the plane arrived =
After his arrival, we have a party. =
=
时态使用重大的规则:(12字原则)
主过从过,主将从现,主现从任
【主将从现】
常见的有以下三种情况:
一、When/if引导的主句是一般将来时,从句用一般现在时。
I'll tell her the good news when she comes back.当她回来的时候,我将把这个好消息告诉她。
If it doesn't rain, he will come here on time.如果不下雨,他会按时来这儿的。
二、如果主句是祈使句,那么从句要用一般现在时。
Don’t laugh at me when I make a mistake. 我犯错误的时候不要笑话我。
三、如果主句是含有情态动词的一般现在时,从句多用一般现在时。
You should be quiet when you are in the reading room. 在阅览室时应保持安静。
【主过从过】
常见的有以下二种情况:
1.直接引语变成间接引语
2.宾语从句中,当主句的谓语动词为过去时态时,从句须用表示过去的某种时态。
例如:
He asked when they would go to the party.他问他们什么时候将去参加聚会。
Miss Green said she had been to Beijing before.格林小姐说她以前曾经去过北京。
【主现从任】
常见的有以下一种情况:
在宾语从句中,当主句的时态为现在的某种时态(一般现在时、现在进行时、现在完成时等)后面从句时态不受主句限制,可选用各种适合的时态。
例如:
Do you know when we'll have a football match?你知道我们什么时候举行足球赛吗?
You know he has gone to Shanghai.你知道他已去上海了。
【特别关注】
1.当宾语从句表述的是客观事实、科学真理、现在的习惯动作以及格言等时,只能用一般现在时。
例如:
The teacher told us that light travels faster than sound.老师告诉我们光速比音速要快。
2.如果主、从句表示的动作是一前一后发生的,则先前的用过去完成,在后的只能用一般过去时态。
When he got there, the train had left. 当他到那儿的时候,火车已经开了。
